Laboratory-grown geometric perfection – this spectacular bismuth crystal displays the brilliant rainbow iridescence and stepped crystal formations that make bismuth a modern collector favorite. The geometric precision rivals nature’s finest crystal work.

What You Get:

• Large bismuth crystal cluster
• Brilliant rainbow iridescent colors

While natural bismuth rarely forms large crystals, controlled laboratory conditions allow these spectacular formations to develop. The rainbow colors result from a thin oxide layer that forms on the crystal surface, creating interference patterns that shift as viewing angle changes.
